Figure 1

Favored regions and exclusion contours in the $(M_{\varphi },{\sigma }_p)$ plane for the standard case $f_n/f_p=1$ (top panel) and the case $f_n/f_p=-0.71$ (bottom panel). The light grey contour is the $3\sigma$ favored region by DAMA/LIBRA [28] assuming no channeling [29] and that the signal arises entirely from $\mathrm{Na}$ scattering; the dark grey region is the 90% CL favored region by CoGeNT; the dashed line is the exclusion plot by CDMS-II Soudan [13]; and the black and top line at smaller dark matter masses are, respectively, the exclusion plots from the Xenon10 [14] and Xenon100 [15] experiments. The common region passing all the constraints is shown in darker grey.Reuse & Permissions
